These are terrain-alterable overlays for use with VASL.  Place the following
files in a subdirectory named "overlays" in the boards directory:

ovrEF
ovrOC
ovrBE

	For the Ocean and Beach overlays, place them like ordinary
overlays.  Place dummy boards where the overlays should go and use the
coordinates on the dummy boards, using overlay hex xx01 (i.e. 1001,
2001, etc.) for hex '1' and hex xx02 for hex '2'.  You will probably
have to get out the physical components to determine how to place
them.
